Hi all,

This patch will add armv7ve support to gcc. Armv7ve is basically a 
armv7-a architecture profile with Virtualization Extensions. Additional 
test cases are also added.

With this patch and to keep backward compatibility with old assembler, 
the following asm header will be generated when -march=armv7ve option is 
presented.
.arch armv7-a
.arch_extension virt
.arch_extension idiv
.arch_extension sec
.arch_extension mp

This is a amendment to a previous patch: 
http://gcc.gnu.org/ml/gcc-patches/2013-11/msg02365.html
No new __ARM_ARCH_7VE__ is defined. Instead, __ARM_ARCH_7A__ is defined 
with additional extensions (e.g. __ARM_ARCH_EXT_IDIV__) when arch is set 
to armv7ve.


Okay for trunk?

Regards,
Renlin Li

Mind adding this to the release notes?

Hi Gerald,

Sorry for the late reply!
We're working on a list of all the ARM-related changes in 4.9. This will 
also be included.

Kind regards,
Renlin

This is Ok since this was submitted quite sometime back.

Sorry about the delay - I've been on holiday.
